We (the sheeple) should vote for all federal judges. The higher the court, the longer the term. But all voted in or out after a period.
FL has merit retention for the FL SC judges.
They usually get retained with 80% of the vote. They don't even bother to campaign.
In many places it is professional suicide for a lawyer to run against a sitting judge.
Even if elected you are elected for as long as you want the seat. (or mandatory retirement, which you bypass with taking protracted special cases.)
